I don't have any idea how to make it work but I do question doing NAT on 
a CAT to begin with.  Even if it did support NAT it would be done in 
software.  Someone firing up a simple BitTorrent client would likely be 
enough to bring it to its knees.  It's like doing NAT on the Sup in a 
65/7600.  A few Mbps is enough to bring the box down.  If NAT is a 
requirement then I'd look at doing it with a firewall or real router.

Best of luck
